Overview

74HC4520-Q100; 74HCT4520-Q100 Dual 4-bit synchronous binary counter Rev.
3 — 9 October 2020 Product data sheet 1.
General description The 74HC4520-Q100; 74HCT4520-Q100 are dual 4-bit internally synchronous binary counters with two clock inputs (nCP0 and nCP1).
They have buffered outputs from all 4 bit positions (nQ0 to nQ3), and an asynchronous master reset input (nMR).
The counter advances on either the LOW-to-HIGH transition of nCP0 when nCP1 is HIGH.
It also advances on the HIGH-to-LOW transition of nCP1 if nCP0 is LOW.
Either nCP0 or nCP1 may be used as the clock input to the counter.
The other clock input may be used as a clock enable input.
A HIGH on nMR resets the counter (nQ0 to nQ...
